Claims.

This invention relates to a fastener and more particularly to a stampedsheet metal fastener for insertion in an opening for securing finishedobjects to supporting surfaces.

A primary object of the invention is to provide a spring fasteningdevice which is designed to secure a molding or other decorative part toa supporting member through an aperture in the supporting member.

Another object of the invention is to provide a stamped sheet metalfastener for insertion into an aperture in the supporting member and astamped sheet metal locking member which cooperates between thesupporting member and the fastener.

A further object of the invention is to provide spring arms struck fromthe locking member to hold the locking member in position and providemeans for closing the aperture.

A still further object of the invention is to provide spring arms struckfrom the body of the fastener to receive a hollow molding withspacedinwardly turned flanges, the spring arms being so formed as to hold themolding or, other decorative part securely to the supporting member.

Other objects and advantages of the invention will more fully appearfrom the following description taken in connection with the accompanyingdrawings, in which:

Fig. 1 illustrates an improved molding fastener in fastened position toa supporting member; the fastener being shown in side elevation with thesupporting member and applied molding in section;

Fig. 2 illustrates a modified form of the invention showing the fastenerin side elevation with the supporting member and applied molding insection;

Fig. 6 is a view corresponding to Fig. 1 but showing a further modifiedform of the invention.

Referring to the drawings, It represents a hollow molding or trim stripprovided with the usual spaced inwardly turned flanges l2 and It whichis to be mounted on an apertured support, it. Preparatory to theassembly of the molding on the supporting surface, formed fasteners G8are inserted in the molding between the inwardly turned flanges 12 andM. The fasteners 18 are positioned in spaced relation'relative to theaper- Detroit, Mich., assignor to Ferndale, Mich.

to the supporting suris so formed as to pertures 2t and are applied faceIt. Each fastener 18 mit a locking member 26 to be forced between aportion of the fastener l8 and the supporting member l6, thereby holdingthe fastener 18 securely in position.

Referring to the form of the invention shown in Figs. 1, 3 and 5, thefastener 18 comprises a one piece sheet metal stamping, preferably ofspring steel, having a base 28 of arcuate form. The center portion ofone end of the base 28 is struck out at an acute angle forming an arm 32which cooperates with the underside of the molding H) to hold thefastener firmly in alignment with the aperture in the supporting memberit, to which the molding is to be applied.

The center of the opposite end of the base portion 28 of the fastener isis struck out to form an arm 22 which is to be inserted in the aperture29 of the supporting member It. The end of the arm 22 is bent upwardlyin the form of the letter S. The upper half forms a resilient lockingfinger $2 to form a snap receiver for the locking member 26.

The locking member 26 comprises a one piece sheet metal stamping,preferably of spring steel, having a base 34 and outwardly turned ends38 and 40 to facilitate its sliding across the surface of the supportingmember 16, the base 34 resting against the supporting member l6 when thelooking member 26 is in the locked position. The center portion of thebase 34 is struck outwardly to form an arm 36 leaving the base 34substantially in the shape of the letter U. The arm 36 being bent at anobtuse angle 44 forms a positive locking arm to be forced past theresilient locking finger 4 2. A portion 46 of the arm 36 extends alongthe arm 22 of the fastener l8 from the obtuse angle 44, and having anupturned spring finger 48 substantially in the form of the letter V,closing the aperture so that water, sand, or other foreign matter maynot enter.

In the assembly of the device, the fasteners 18 are inserted in thehollow molding with the ends of the base 28 and 3D resting against thespaced, inwardly turned flanges l2 and It. The spring arm 32, pressingagainst the body of the molding, furnishes tension to hold the fastenersecurely in place but, yet allows the fastener to be positioned relativeto the apertures 20 in the supporting member Hi. The arms 22 of thefasteners i8 are then freely inserted through the apertures 20 of thesupporting member 16 with the outer surfaces of the arms 22 resting uponthe edges of the apertures 29. The locking members 26 are pressed overthe arms 22 on the reverse side of the supporting member l6 from thatwhich the molding is fastened. The locking members 26 are pressed theupturned ends 48 of arms 46 have closed the apertures 20. The fastenersI8 are now securely locked in the desired position and the apertures Themolding the supporting member l6.

Referring to a modified form of the invention, Figs. 2 and 4, the arm32' of the fastener I8 is struck out at an obtuse angle to contact themolding l and hold it securely in place; the end 24' of the arm 22' isbent upwardly in an arcuate form to provide a resilient locking finger.The locking member 26' has a base 34 from one end of which an arm 36' isstruck. The arm 36 is bifurcated at its end forming fingers 50 and 52 toprovide a positive locking means in cooperation with resilient lockingfinger 2 3'. From the opposite end of the base 3 is struck a resilientarm 48 which snaps into aperture 20' closing the opening so that foreignmatter may not enter.

After the fastener l8 has been secured in the molding I 0 by thedescribed means, the arm 22' is inserted through the aperture 20. Thelooking member 26 is pressed over the arm 22 until the bifurcated endsnaps over the resilient locking finger 24' and the resilient arm 48snaps into the aperture 20' locking the fastener l8 securely in thedesired position.

Referring to another modified form of the invention, Fig. 6, thefastener I8" is substantially the same as that shown in Figs. 1, 3 and5. The locking member 26" comprises a base 34" from which is struck aning finger 24" to provide a positive locking means for the fastener I8". A resilient arm 48" is struck from the opposite end of the base 34to snap into the aperture 20" closing the aperture to all foreignmatter.

After the fastener l8" has been secured in the molding H)" by thedescribed means, the arm 22" is inserted through the aperture 20''. Thelocking member 26" is pressed over the arm 22" the resilient finger 56snaps past the resilient locking finger 24" and the resilient arm 48"snaps into the aperture 20" locking the fastener I8" securely in thedesired position.

While the two in-terengaging members have been described as beingsecured together by a snap on action and being preferably of resilientmatebending the locking finger 24' between the fingers i] and 52 orbending the locking finger 26" over the finger 56.

The device has form of by the terms of the appended claims.
